 double-somite ornamented with fine pits on dorsal surface as figured 

 (Figure 51 A, B). Seminal receptacle divided into broad anterior and 

 posterior lobes. Caudal rami (Figure 51A,B) parallel, 3.2 times 

 longer than broad; with groups of spinules and hairs along inner 

 margin (Figure 51 A, D); outer terminal seta (IV) and inner terminal 

 seta (V) well developed and heterogeneously ornamented (Figure 

 51 A). 



Antennule 8-segmented; Setal formula 8, 12, 6, 5, 2 + aesthetasc, 

 2, 2 + aesthetasc, 7 + aesthetasc. Coxobasis of antenna (Figure 

 52G.H) with complex ornamentation on caudal and frontal sides as 

 figured; without spinular row on caudal surface near base of two 

 inner setae (arrowed in Figure 52G). 



Basis of leg 1 (Figure 52C) with setiform inner spine reaching 

 midway along terminal endopodal segment; intercoxal sclerite 

 ornamented with 2 spinular rows on posterior surface (Figure 52D). 

 Intercoxal sclerite of leg 2 ornamented with spinular rows on 

 anterior and posterior surfaces (Figure 52J.K). Intercoxal sclerite of 

 leg 3 without spinular row on anterior surface and with 2 spinular 

 rows on posterior surface (Figure 52E,F); coxa with complex orna- 

 mentation on posterior surface as figured (Figure 52E). Intercoxal 

 sclerite of leg 4 (Figure 52A,B) with 2 spinular rows on posterior 

 surface; inner coxal spine with proximal group of setules mainly 

 originating posteriorly (Figure 52B).

Leg 5 (Figure 51C) comprising single free segment, armed with 1 

 long, well developed outer spinulose seta, 1 serrate, strong inner 

 spine, and 1 plumose seta centrally. 



Description of adult male 



Body length measured within same range as original description 

 (Reid, 1987), length of allotype 580 urn, lengths of paratypes 550 

 and 600 urn. Genital, third, fourth and fifth urosomal somites 

 (Figure 53A,B) ornamented with cuticular pits on dorsal surface. 

 Caudal rami shorter than female, about 2. 1 times longer than broad; 

 with complex ornamentation along inner margin as figured (Figure 

 53A,B,D). First segment of antennule armed with 8 setae plus 

 aesthetasc; 1 seta (A) large and modified by ornamentation of strong 

 spinules in proximal and mid sections, tapering to fine point distally. 

 All other appendages as in female except; outer setae of fifth leg 

 plumose (Figure 53C); sixth leg (Figure 53A,C) armed with 1 inner 

 spine as long as second urosomal somite, surrounded by spinules at 

 base; 2 outer setae plumose. 



Variability. The outer margin of inner spine of the female leg 5 

 may be ornamented with a variable number of spinules (Figure 5 1C). 



Differential diagnosis. P. carectum is unique within the genus 

 in carrying ornamentation of spinules along the inner margin of the 

 caudal rami (Figure 51A,D).

 Biological Reserve, Federal District, 15°32'30"S, 47°34'57"W; Wet 

 campo Marsh, Fazenda Agua Limpa, Distrito Federal; Goias, marsh

Redescription of adult female 



Body length measured within same range as in original description 

 (given by Reid ( 1 987) as 570-880 urn, mean = 630). Genital double- 

 somite, second and third abdominal somites ornamented with very 

 fine pits on dorsal and ventral surfaces as figured (Figure 54A,B). 

 Seminal receptacle divided into narrow anterior and broad posterior 

 lobes as figured (Figure 54B). Caudal rami (Figure 54A.B) with fine 

 cuticular depressions on ventral surface. Terminal accessory seta 

 plumose (VI) and 1.5 times longer than posterolateral seta (III); 

 posterolateral seta (III) strong and unilaterally plumose, with spinules 

 along dorsal surface; setae IV and V well developed and heterogene- 

 ously ornamented (Figure 54B). 



Antennule 8-segmented (Figure 55A). Segment 2 and 3 with 

 complex partial suture lines. Segment 2 may be incompletely sepa- 

 rated or with complete separation, best seen in Figure 55A,C,E,F. 

 Segment 3 with partial suture line and spiniform seta. Setal formula 

 8, 12, 6, 5, 2 + aesthetasc, 2, 2 + aesthetasc, 7 + aesthetasc. 

 Coxobasis of antenna (Figure 55B,D) without spinular row on 

 caudal surface near bases of inner setae (arrowed in Figure 55D). 



Coxa of leg 1 lacking spinular row on posterior surface near 

 intercoxal sclerite (Figure 56G). Intercoxal sclerite of leg 2 

 ornamented with spinular row on anterior surface (Figure 56B); 

 without spinular row on posterior surface (Figure 56A). First and 

 second exopodal segments lacking spinular row on posterior surface 

 (Figure 56B). Intercoxal sclerite of leg 3 with spinular row on 

 anterior surface (Figure 56E) and 2 spinular rows on posterior 

 surface (Figure 56F). Intercoxal sclerite of leg 4 without spinular 

 row on anterior surface (Figure 56D) and with 2 spinular rows on 

 posterior surface (Figure 56C); coxa without mid-distal spinular row 

 on posterior surface (arrowed in Figure 56C).
